• Where should I report bugs and other problems with Emacs?

  The correct way to report Emacs bugs is by e-mail to [email protected]. Anything sent here also appears in the newsgroup gnu.emacs.bug,

• What are appropriate messages for gnu.emacs.help, gnu.emacs.bug,

  The file etc/MAILINGLISTS discusses the purpose of each GNU mailing-list.

• What is the real legal meaning of the GNU copyleft?

  The real legal meaning of the GNU General Public License (copyleft) will only be known if and when a judge rules on its validity and scope. There has never been a copyright infringement case involving the GPL to set any precedents...

• How can I force Emacs to scroll only one line when I move past the bottom of the screen?

  Customize the `scroll-conservatively' variable with `M-x customize-variable scroll-conservatively ' and set it to a large value like, say, 10000. For an explanation of what this means, *note Auto Scrolling: (emacs)Auto Scrolling.

• What do these mean: etc/SERVICE, src/config.h, lisp/default.el?

  These are files that come with Emacs. The Emacs distribution is divided into subdirectories; the important ones are "etc", "lisp", and "src".

• How do I turn on syntax highlighting?

  `font-lock-mode' is the standard way to have Emacs perform syntax highlighting in the current buffer.

• How do I delete menus and menu options?

  The simplest way to remove a menu is to set its keymap to `nil'.

• How do I read topic XXX in the on-line manual?

  When we refer you to topic XXX in the on-line manual, you can read this manual node inside Emacs (assuming nothing is broken) by typing this: C-h i m emacs RET m XXX RET

• What does "M-x command" mean?

  "M-x command" means type M-x, then type the name of the command, then type RET.

• What can I do if my name has been registered by someone else?

• What are the different domain types for?

  .com,.ac.uk,.gov.uk,.net.uk,.plc.uk, .ltd.uk,.org.uk,.co.uk,.org,.net

• When my domain is due for renewal what will it cost?

  Our charges for domain name registration (.com, .net, .org and .uk domains) normally cover the domain for 2 years and include the central registrars fees.

• Are my registration details "private"?

  Firstly any payment details (credit card numbers etc.) you give us will be kept private and confidential.

• Once a name is registered - who "owns" the domain name?

  No one "owns" a domain name any more than someone "owns" a telephone number. The domain name "registrant" is the person or organization listed at the top of the WHOIS database record.

• Can I transfer my domain name elsewhere?

  Yes - you can transfer your domain name at any time - we would hate to lose you but there is no charge to transfer.

• What do I get when I register?

  The name will be registered with the domain name registrar.Your domain name records will be setup on a primary and two secondary DNS servers

• Who are the domain name registrars?

  A domain name registrar is an organisation that holds the central records (database) for all the domains they administer. They are often government owned or sponsored.

• Where does ICANN come in?

  ICANN is responsible for managing and coordinating the DNS to ensure universal resolvability. ICANN is the global, non-profit, private-sector coordinating body acting in the public interest.

• What is a domain name

  A domain name is a "unique" name used to identify and locate computers on the Internet. Internet domain names provide a system of easy-to-remember Internet addresses which are translated by DNS (Domain Name Servers) into numeric IP (Interne...

• What does "wire_read: unexpected EOF" mean?

  This error message should say something like "the plug-in (or the main GIMP app) I was talking to has exited before returning any results, so I assume that it has crashed."

• Does the GIMP have scanner support?

  Yes. You can run xscanimage, the front end to SANE (Scanner Access Now Easy), either as a GIMP extension or in stand-alone mode.

• Why does the GIMP complain "unresolved symbol: _gimp_message"?

  This is caused by attemping to use a pre-1.0 libgimp with gimp 1.0. The gimp_message() was added in 1.0, and is required by 1.0 to operate.

• Why does the GIMP complain about missing or wrong versions of libraries?

  There are a couple of solutions. The best one, if you have superuser access on your system, or a cooperative system administrator, is to add the GIMP's library directory to the system library configuration. To do this, edit /etc/ld.so.conf...

• What are layers?

  hese are similar to the layers found in tools such as Adobe's PhotoShop[tm]. Think of a stack of slides or filters, such that looking through them you see a sort of composite of their effects.

• Is GTK+ still under the aegis of GIMP? Was it ever?

  GTK was developed solely for GIMP, initially. Towards the end of the 0.99 development cycle in 1998, GTK was split from being bundled with GIMP to being a separately available library.

• Is GIMP a GNOME application?

  Not really. It doesn't use the GNOME application framework. The only thing it has in common is GTK

• What is this GIMP?

  The ``GNU Image Manipulation Program''

• GIMP appears to hang while loading fonts. What's going on?

  If it's the first time you've run GIMP, it may be indexing your fonts. This may take a few minutes to complete.

• When using Gimp image software, how do I save without running into an error message?

  you shouldn't be getting a error message while saving.. try reinstalling gimp or check the gimp website for known errors and patches... if they don't have anything you should report the error.

• Discuss about the stack based buffer over run detection in VC++?

  Stack based buffer over run protects the program from executing malicious code. Function epilogue code checks the returned cookie for similarity if there is a mismatch it stops executing the code. It also moves around the stack which makes...

• Explain about typedef?

  A type predicate takes one or more arguments and it is a template. If a type predicate is true it is publicly derived directly or indirectly from true type def. In case it is false it is publicly derived from false type def.

• Describe about unordered_map?

  Unordered_map defines container template classes such as unordered map and unordered multimap template. Under declarations unordered map Class and unordered multimap class are defined. These classes store hash table.

• Explain about tuple in visual c++?

  Tuple defines instances of objects in varying types. Declarations, template functions and functions are defines in tuples. In class there are three elements they are tuple class, tuple size Class and tuple element Class are defined in Vis...

• Explain about the function regex?

  This defines a template to parse certain regular expressions. It also defines several classes and functions to search text that is matching a regular expression object. There are many declarations, type definitions, template functions, and...

• Explain about functional?

  Functional defines a huge number of templates which help construct function objects which defines operator. Function pointer can be described by a function object. It stores information which can be accessed during the functional call.

• Name some important features of VC++?

  Some of the important features of VC++ are as follows 1) Smart pointers 2) New containers 3) Expression parsing 4) Polymorphic function wrappers 5) Type traits and sophisticated random number generators.

• Explain about CWinThread class?

  If you want to provide a window to an application it is imperative to create a thread which can be done using CWinThread. A public member variable is used with CWinThread is m_pMainWnd. The main advantage which you can get when using this t...

• Explain about CFrameWnd?

  MFC has an extensive set of classes present in its library out of which CFrameWnd is one of those. This is a very important class and it is used frequently. User defined classes can be created by CFrameWnd. To create a windows frame CFrameW...

• Explain about frames?

  Frame describes about the borders, dimensions and location of the window. Two types of MFC applications are present which use a frame. Application using frames use a concept known as Document/View architecture. This architecture allows a ce...

• Explain about InitApplication()?

  To display an output for a certain application programmers have to use InitApplication() method. InitApplication is a Boolean method. This function outputs a true if an application gets succeeded. If it did not succeed it displays a false c...
